Me: “Okay, if you can send me a screenshot of the error, I think I know the problem.”

(My colleague sent me a screenshot that consisted of the following: a print screen of the error, pasted into Word so it was shrunk portrait, printed out, scanned, and saved as a .tif file. The file was then attached to an email and sent to me. The colleague is a lovely person but really struggles when it comes to common sense.)
